Application filed January 12, 1918. Serial No. 211,581.

To all whom it may concern Be it known that I, HARVEY E. EASLY, a citizen of the United States, residing at \Vaterloo, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Oxygen-Inhaling Devices; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an oxygen inhaling device.

The object of the present invention is to provide a simple, practical and efficient oxygen inhaling device adapted to enable persons afiiicted with consumption of the lungs to breathe in air containing a greater amount of oxygen than the ordinary atmospheric air, thereby enabling such persons to ob tain the efiect of the oxygen without the expense incident to traveling to places where the air naturally contains the desired proportion of oxygen.

It is also an object of the invention to provide an oxygen inhaling apparatus of this character equipped with means for enablin the oxygen to be mixed with the air inhaled by a patient in the desired proportion as required by the condition of the patient.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to with out departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

Figure 1 is a horizontal sectional view of an oxygen inhaler constructed in accordance with this invention.

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a similar view on the line 33 of Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the oxygen inhaling apparatus comprises in its construction a receptacle 1 a filling aperture 2 and having a closure cap or plug 3. 'The oxygen may be introduced into the receptacle in any preferred form and the said receptacle is provided with a tapering discharge tube 4 having a valve plug 5 located intermediate of the ends of the discharge tube and mounted in an enlargement 6 of the said tube. The valve plug is provided with an opening 7 and is adapted to be partially rotated to entirely cover the opening or partially cover the same or fully expose the opening so that the supply of oxygen may be cut off when it is not desired to use the same and the required amount of oxygen ma be mixed with the air. Various other orms of controlling means may be employed as will be readily understood and the discharge tube of the oxygen receptacle extends into an air inlet and mixing tube 8 provided with a pair of bulb shaped outlets 9 having apertures 10.

The tapered discharge tube of the oxygen receptacle terminates short of the bulb shaped outlets which are adapted to fit in the nostrils of the patient so that when the patient inhales through the apparatus air and oxygenwill be drawn into the lungs. By this construction the lungs of a consumptive may be given an oxygen treatment and the quantity of oxygen mixed with the air may be varied to suit the condition of the patient and the apertures 10 may be made of any desired size- The inner end 11 of the air inlet tube is of any desired form and size provided with open and preferably flared as shown, and the air inlet tube is supported by longitudinally outer terminals 13 and 14 connected respectively with the receptacle and with the air inlet tube adjacent to the outer end thereof. Any other suitable supporting means may of course be employed and if desired the outer end of the air inlet tube may be provided with any suitable means for supporting the end of the discharge tube 4 in a central position.

What is claimed is:

1. An inhaling device of the class de scribed including a receptacle provided with a discharge tube having means for controlling the discharge of oxygen from it, an air inlet tube open at its inner end and receiving the outer portion of the discharge tube and provided with an outlet, andspaced longitudinal supporting members located at opposcribed including a receptacle provided with:

a discharge tube having means for controlling the discharge of oxygen from it, an air lnlet tube open at lts mnerendandrecewing the outer portion of the discharge tube and provided With, an outlet; andspaced longitudinal supporting members located at opposite sides of the saidtu-be and connected at their inner ends With a receptacle and at their outer terminals with the air inlet tube, said inlet tube having its inner end flared 15 and fitted against the supporting members intermediate of the ends thereof.

In testimony whereof I atfix my signature in presence of two Witnesses.
